VEHICLE-SPRING GEAR.

T all wbOm/ may COHOSWL: lper ends of these rods are connected by ilatBe it known that I, PHILIP L. RAMsEY, a plates F. Beneath these platesare arranged citizenof the United States, residing at Schomovable platesM, having eyes in their ends choh, in the county of Logan and State ofwhich slide upon said vertical rods, and on '5- 5 Kentucky, haveinvented a new and useful thelatterarearranged strong expansivecoiledVehicle-Spring Gear, of which the following springs S, which rest attheir lower ends upon is a specification. the perch (the front oneresting upon a washer This invention relates to carriages and waglVabove the upper eye c' of the U-shaped ons, andmore especially to thesprings thereof; arm U) and bear at their upper ends beneath 6o ro andthe object of the same is to produce an the plates M. The latter areprovided at their improved arrangement of springs, whereby centers withdepending eyes t', in which are the wagon or carriage body will befirmly suphung the centers of yokes Y, whose arms exported, but yetpermitted a greater degree of tend thence downwardly and outwardly, asmotion than formerly, over rough roads. shown. 6 To this end theinvention consists of the de- Secured to the bottom of the body at itstails of construction hereinafter more fully four corners are strapswhich extend outdescribed and claimed, and as illustrated on Wardly andform ears E, and these ears are the accompanying sheet of drawings,whereconnected across the ends of the body by horiin zontal rods H, andto these ears are also con- 7o 2o Figure l is a general perspective viewof a nected the lower ends of the yokes Y.

This movement is permitted by thesprings S', and at the same time the cushioning effect of the verticalsprings is not interrupted. Hence the body B will always stand level,even though one wheel may pass over an obstruction nearly or quite afoot in height. p

I do not limit myself to the exact details of construction shown anddescribed inI this application, as considerable change may be madetherein without departing from the spirit of my invention. For instance,the speciic means by which I pivot the front axle so as to permit itsvertical as well as its horizontal motion may be useful by a slightadaptation of parts in other connections, although I prefer to employ ithere, and the rubber buf` fers or washers R, which I should have saidare employed at each end of each of the springs, might be omitted,although their use causes the device to be practically noiseless.

What is claimed as new is-` 1. In a device of the character described,the combination, with the perch having a bifurcated front end, an eyepivoted therein on the king-bolt and having a forwardly-extending shank,and a U-shaped arm having eyes at its rear end pivotally mounted on saidkin g-bolt above and below the perch, the front end of said shank beingconnected with the bend of the arm, of the front axle extending throughsaid arm and pivotally mounted on the shank, as and for the purpose setforth.

2. In a device of the character described, the combination, with theperch, vertical rods rising therefrom in pairs and connected by platesat their upper ends, and the body standing between said pairs, of coiledsprings on said rods, moving plates above their upper ends belowtheconnectingplates, eyes depending from the centers of the moving plates,and yokes connected at their centers to said eyes and at their lowerends to the corners of the body, as and for the purpose set forth.

3. In a device of the character described, the combination, with theperch, vertical rods rising therefrom in pairs and connected by flatplates at their upper ends, moving plates having eyes loosely mounted onsaid rods, a coiled spring between the perch and each moving plate andupon each rod, a depending eye at the center of each plate, and verticalguides rising from the perch between the lower ends of each pair ofrods, of a body mounted between said pairs of rods, ears at the fourcorners of said body, horizontal rods connecting said ears at the endsof the body and passing through said guides, a yoke at each end of thebody connected at its ends to said ears and at its center to saiddepending eye, washers on said horizontal rods at each side of eachguide, and a coiled expansive spring between each washer and eye on thehorizontal rods, all as and for the purpose set forth.

4t. In a device of the character described, the combination, with theperch, vertical guides rising therefrom, a body between said guides, andsprings, substantialy as described, for cushioning the vertical movementof the body, of ears at the four corners of the body, horizontal rodsconnecting said ears in pairs across the ends of the body and extendingthrough said guides, washers on said rods adjacent the guides, and acoiled expansive spring on said rod between each washer and eye, as andfor the purpose set forth.

5. In a device of the character described, the combination, with a perchhaving a bifurcated front end, a king-bolt passing therethrough andrising vertically therefrom in front of the wagon-body, an eye pivotedin said bifurcation upon the king-bolt and having a forwardly-extendingshank, a U shaped arm having eyes at its forward ends pivotally mountedon the king-bolt above and below therperch, the front end of said shankbeing connected with the bend of the arm, and the front axle extendingthrough said arm and pivotally mounted on the shank, of a moving plateupon said king-bolt, an expansive springbetween the upper eye of saidU-shaped arm and said moving plate, and connection between the latterand the wagon-body, all as and for the purpose set forth.

6. In a device of the character described, the combination, with theperch, vertical rods rising therefrom in front and in rear of the body,moving plates mounted loosely on said rods, and springs between saidplates and perch, of connections, substantially as described, betweensaid plates and body, as and for the purpose set forth.

7. In a device of the character described, the combination, with theperch, vertical rods rising therefrom in front and in rear of the body,moving plates mounted loosely on said rods, springs between said platesand perch, and vertical guides-rising from the latter, of ears at thecorners of the body, connections between said ears and plates, andexpansive springs between said guides and ears, all substantially as andfor the purpose hereinbefore set forth.

In testimony that I claim theforegoing as my own I have hereto affixedmy signature in presence of two witnesses.
